CVE-2026-59865
Published:July 16, 2026
Updated:August 04, 2026
Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.32.5, "kiota info" read x-ms-kiota-info.languagesInformation.<language>.dependencyInstallCommand plus dependency name and version values from an OpenAPI description and presented the spec-supplied command as Kiota's recommended install command, allowing an attacker-controlled or compromised description to cause command injection when the suggested command was run manually or through the Kiota VS Code extension's kiota info --json dependency-install flow. This issue is fixed in version 1.32.5.
